This paper presents the application of well testing data to determine the parameters of fracture porosity seepage flow in carbonate reservoir by using multi-media seepage flow interpretation model,which is based on the productivity data of well testing,i.

To apply image processing technique into rock fracture recognition, the key and hardest task is to auto-sewing fractures on the the rock fracture images, and the newly developed rock fracture sewing algorithm is very effective for sewing rock fractures, it has been tested in a laboratory and works satisfactorily.
